Substance Uses Mediate Differently in Relation between ADHD and Suicidality: Study among New Soldiers in Taiwan
Yueh-Ming Tai, Li-Kung Yang, Hui-Nien Yang
Background: Attention deficit/hyperactivity disorder and substance use have
been considered as strong predictors for depression, opposition, and suicidal behaviors‒suicidal ideation (SI), suicide attempt (SA) and deliberate self-harm. The
details in associations among various substance use are still unknown in military
population. Methods: Totally, 1,120 new soldiers participated and completed copies of self-report questionnaire including demographic data, Swanson, Nolan, and
Pelham, Version IV Scale-Chinese version (SNAP-IV); the Adult Self-report Scale
Inventory-4-Chinese version (ASRI-4); and Beck Depression Inventory, 2nd edition (BDI-II). Results: The uses of substance, including betel nut, significantly
raised the risks of all three suicidal behaviors (all p < 0.001). The paths of ADHDdepression-suicidal behaviors and ADHD-opposition-depression-suicidal behaviors were significantly superior to other paths (all p < 0.05). Past use of hypnotics
was significantly superior to other types of used substances for its highest indirect
effects on SI and SH (all p < 0.05). Conclusion: In line with other studies, this
study confirms the mediation effects of substance use, especially hypnotics, in the
associations between ADHD and SI, SA, and DSH behaviors. Our findings indicate that screening for suicidal tendency among those new soldiers with substances
use, depression, opposition, and recalling either ADHD symptoms are all
essential.
